...at first.. he loved the stretchyness... He then slowly streched the material, in a more comfortable pace... ...and then he found out there were still some "remnants" left from the owner in the panties...
I wonder what happens next... Maybe he puts his head in it and you can see his nose sniffing about in it... Or maybe first just gently sniffing with his nose gliding above the still streching panties. Hehehe...
